Abstract: ??? Filed: August 4, 1978 BALANCED WASTE HEAT RECOVERY   AND DISSIPATION SYSTEM                 ABSTRACT OF THE DISCLOSURE     A system for recovering and utilizing, to a controlled and variable extent, waste heat from a coolant fluid.  The amount of heat recovery varies in proportion to the marginal costs associated therewith.  Heat laden coolant passes through an in-terior heat exchanger where heat may be extracted in varying amounts from the coolant by a thermostatically-controlled air mover, the air mover admitting outside air past the interior heat exchanger.  The coolant proceeds to an exterior wet surface heat exchanger where residual heat is concurrently extracted from the coolant by a thermostatically-controlled combination of ambient air, recirculated ambient air, and water spray.  The coolant then returns to the beginning of its cycle.  The temperature of out-side air is the principal variable determining the proportion of heat recovered by the interior heat exchanger and the proportion extracted by the exterior heat exchanger. The total heat ex-tracted reduces the coolant temperature to a predetermined operat-ing level.

Abstract: A B S R A C T       In a process for production of aluminium metal described in Patent Application No.278947 carbon monoxide gas is evolved at very high temperature through reaction of aluminium carbide and alumina in a high temperature zone of the system.   This gas is cooled by contact with a molten alumina slag at a lower temperature to cause back reaction of contained aluminium suboxide and A1 vapour and consequent heat transfer to the contacted molten alumina slag.       A body of molten alumina slag is maintained in a pretreatment zone, to which carbon and alumina feed are introduced and the carbon monoxide gas is led into the pretreatment zone.   Excess slag, resulting from such introduction of feed and from gaseous back reaction, spills over into a low temperature zone of the system to augment the circulating slag stream.

Abstract: MICROPROCESSOR CONTROLLED ROLL FILM MICROFICHE READER    Abstract of Disclosure An electronically controlled photographic image utilization device is arranged to transport a roll of microfilm having all images printed thereon in separate photographic areas, each area being arranged in a microfiche-type format.  The photographic image utilization device has an automatic call-up feature so that any given photographic area may be selected and protected responsive to the push of a button, the operation of a rotary switch or both.  A special bar code is printed along the edge-of the film and used in conjunction with a closed loop film control system to eliminate the need for precise, clock controlled synchronization between the film transport and the code reading.  Preferably, the bar code is read by optical electronic sensors.  Responsive thereto, the electronic control system accurately positions a selected photographic image, on the mocrofilm within a viewing area.  Thereafter, and while the film transport is being held stationary, any image on the microfilm may be selected for projection by a manual movement of a simple lens positioning mechanism which is small, compact, and easily moved.  The reader may also be operated manually so that the automatic controls may be by-passed, if desired.

Abstract: APPLICANT: VOLVO BM AB            TITLE:  VEHICLE WITH BOGIE-MOUNTED WHEELS AND RAISING          DEVICE FOR A PAIR OF WHEELS     ABSTRACT OF THE DISCLOSURE      A vehicle such as a dumper with articulated steering has a load-carrying portion supported by two wheel-pairs mounted on bogies. One wheel-pair can be raised from the ground while the other, still on the ground, has softer suspension. In a vehicle with its two portions relatively swingable around a longitudinal axis, the two wheels on the ground are coupled so as to move relatively identically in relation to the vehicle frame. With one wheel-pair raised and the other suspended, the vehicle is still laterally stable. Spring suspension is obtained by tipping the bogies using a mechanism actuated by a hydraulic cylinder with a gas accumulator attached to the feeder line of the hydraulic cylinder. Gas spring suspension thus occurs only when one wheel-pair is raised.

Abstract: INJECTIVITY PROFILE LOGGING FOR TWO PHASE FLOW   (D#74,463-F) ABSTRACT OF THE DISCLOSURE            Fluid injectivity within an interval in a well bore is determined by injecting into the well two fluid streams, one of which flows down the tubing and one of which flows down the annulus, one of said fluid streams containing a radioactive tracer.  The sum of the two fluid flow rates is held constant while each flow rate is varied against the other.  At each different pair of flow rates,  a stable interface is formed between the fluid containing the radioactive tracer and the fluid without it.  The position of this stable interface at each different set of fluid flow rates is measured by a conventional gamma ray well logging tool,  and from the series of such measurements an injectivity log over the measured interval can be determined.  The injectivity profiles for the two components of a two phase fluid flow system are determined by conducting the survey with a radioactive tracer soluble in the gas phase and repeating the survey with a radioactive tracer soluble in the liquid phase.                             -I-

Abstract: ABSTRACT OF THE INVENTION          Solvent Recovery Process This process provides a means of re-claiming useful materials from liquid waste products comprising solutions or dispersions of polymer in organic solvents.  The liquid waste is dispersed in particulate form in water and that dispersion distilled to recover the organic solvent. A feature of the process is that the residue is a free-flowing slurry of solid particles which is readily discharged from the processing equipment and can be re-cycled in suitable products.  To achieve this the liquid waste must be adapted to be heat convertible by the processing conditions, to the point where it is insoluble in acetone on curing for 60 mins at 100°C.
